int32	FindClosestFaceAndVertices ( const FVec3& Position, TArray< FVec3 >& FaceVertices, FReal SearchDist )	Finds the first intersecting face at given position
Pair< FVec3,...	FindClosestIntersection ( const FVec3& StartPoint, const FVec3& EndPoint, const FReal Thickness )
Pair< FVec3,...	FindDeepestIntersection ( const FImplicitObject* Other, const TParticles< FReal, 3 >* ..., const FMatrix33& OtherToLocalTrans..., const FReal Thickness )
Pair< FVec3,...	FindDeepestIntersection ( const FImplicitObject* Other, const TBVHParticles< FReal, 3 >..., const FMatrix33& OtherToLocalTrans..., const FReal Thickness )
FVec3	FindGeometryOpposingNormal ( const FVec3& DenormDir, int32 FaceIndex, const FVec3& OriginalNormal )	Given a normal and a face index, compute the most opposing normal associated with the underlying geometry features.
int32	FindMostOpposingFace ( const FVec3& Position, const FVec3& UnitDir, int32 HintFaceIndex, FReal SearchDist )	Returns the most opposing face.

uint32	GetTypeHash()
const FName	GetTypeName ( const EImplicitObjectType InType )
FName	GetTypeName()
bool	HasBoundingBox()
bool	IsConvex()
bool	IsPerformanceWarning()
bool	IsUnderlyingUnion()	This is strictly used for optimization purposes.
bool	IsValidGeometry()
FVec3	Normal ( const FVec3& x )	Explicitly non-virtual. Must cast to derived types to target their implementation.
bool	Overlap ( const FVec3& Point, const FReal Thickness )	This gives derived types a way to do an overlap check without calling PhiWithNormal todo: this api is confusing.
FString	PerformanceWarningAndSimplifaction()
FReal	PhiWithNormal ( const FVec3& x, FVec3& Normal )
bool	Raycast ( const FVec3& StartPoint, const FVec3& Dir, const FReal Length, const FReal Thickness, FReal& OutTime, FVec3& OutPosition, FVec3& OutNormal, int32& OutFaceIndex )	This gives derived types a way to avoid calling PhiWithNormal todo: this api is confusing.

void	Serialize ( FArchive& Ar )
void	Serialize ( FChaosArchive& Ar )
void	SerializeImp ( FArchive& Ar )

FString	ToString()
void	Track ( TSerializablePtr< FImplicitObject >..., const FString& DebugInfo )	Turn on memory tracking. Must pass object itself as a serializable ptr so we can save it out.
